  2. BCarbon, hydrogen and nitrogen
  3. CCarbon, nitrogen and sulfur
  4. DHydrogen, oxygen and phosphorus

In the Hershey–Chase experiment, viruses were labelled with radioactive phosphorus in their DNA or radioactive sulfur in their protein. Only the phosphorus entered the infected bacteria. What did this show?

  1. ADNA, not protein, is the genetic material of the virus
  2. BProtein, not DNA, is the genetic material of the virus
  3. CViruses contain no DNA at all
  4. DBacteria take up any radioactive substance
8.Trudny

An old idea says giraffes got long necks because each one stretched to reach leaves and passed the longer neck to its young. Why is this idea rejected?

  1. AOnly plants can pass on traits to offspring
  2. BGiraffes do not eat leaves from tall trees, so stretching is not needed
  3. CChanges acquired in a lifetime are not passed on in the genes
  4. DNeck length is not affected by any genes
